My system - KH10 63Amp CB, EQ4800 42kw battery, 80Amp House Main Circuit Breaker before when on KH10 Version 1.67 Master could import form grid at around 17.5kwh to house.
After the upgrade to Master V1.69 the max import from grid to house is around 63Amp/14.6kwh. The Inverter has the max import current still set at 80Amp and max power import still set at 20000W. In fox ess cloud 2.0 i have max ImportPowerLimit 20Kwh.
However the system is clearly limiting import power from grid down to around 63Amp/14.6kwh.
Has anyone else had this issue since upgrading for KH10 to Master 1.69/ Slave 1.03/ARM/Manager 1.64????
Can Fox Ess remove this imposed limit on my house grid load? Which appears to be effecting any KH10 inverter above 1.67 Master firmware level, as confirmed with other users. FOX ESS have no right to limit the power to the house, only that to the inverter.
Hi FOXESS it has been a month and version 1.69 has a hard grid import limit of 63Amps.
Which firmware version will remove the limit so users can get back to allowing the KH10 system to import up to 80amps to the house approx 40amps to charge battery at 10kw and 40amps to power additional house loads such as ev charger aircon etc?

I'm not familiar with any hard grid limit myself - and normally you can adjust the import limits under Settings (password = 0,0,0,0) then on-grid, Export Control and depending on the firmware there are 2 options ImportLimitCurr (set to 80 or 100A to match your incoming fuse) and ImportLimitPwr (normally set to ImportLimitCurr * 230V).
If there is a hard limit imposed you would need to email them on your regional email address

Thank-you will do.
There is a hard limit which has been introduced on kh10 inverters ( I believe incorrectly) from version 1.69 master firmware for grid import of 63amps, so even if you have setup 80amps/20kw which worked on 1.67 firmware it is restricted down to 63amps in firmware 1.69, even though the inverter settings still show 80amp grid import current and 20kw grid import kw.
